Answer: x=6
The two angles shown in each are complementary because they add up to 90°.
10 & 12 would be supplementary to one another because they would add up to 180°.
Step-by-step explanation:
We know that on both 10 & 12 the angles add up to equal 90° so...
10. 8x+7x=90
15x=90
x=6
12. it's the same in pic as 10
The two angles shown in each are complementary because they add up to 90°.
10 & 12 would be supplementary to one another because they would add up to 180°.
Answer:
45 cm²
Step-by-step explanation:
12b-15>21
+15 +15
12b > 36
----- ----
12 12
b = 3
You subtract 7% from 32=29.76
Then you subtract 8% from 29.76=27.379
